Title
(EN) PASSIVE VARIABLE STIFFNESS DEVICE FOR VIBRATION ISOLATION
(FR) DISPOSITIF PASSIF À RIGIDITÉ VARIABLE POUR ISOLATION DES VIBRATIONS
Abstract
(EN)
Described and shown are passive variable stiffness devices, which are of compact design and configured to produce a restoring force that varies optimally with the isolator displacement when subjected to vibration-inducing loading.
(FR)
L'invention concerne des dispositifs passifs à rigidité variable, qui présentent une conception compacte et qui sont conçus pour produire une force de rappel qui varie de manière optimale avec le déplacement de l'isolateur lorsqu'il est soumis à une charge induisant des vibrations.
